portions or habits that they are unsatisfactory guides in deter- 
mining how the bones were articulated, and are of but little 
use in posing the limbs and other parts of the body in positions 
that they must have taken during life. Nor among the higher

appearance or habits ot life to those which we have been obliged 
by the study of the skeleton to ascribe to the Brontosaurus. 
As far as the backbone and ribs were concerned, the articu- 
lating surfaces of the bones were a sufficient guide to enable us 
to pose this part of the skeleton properly. The hmb-joints, 
however, are so imperfect, that we could not in this way make 
sure of having the bones in a correct position. The following 
method, therefore, was adopted: 
A dissection and thorough study was made by the writer, 
with the assistance of Mr. Granger, of the limbs of alligators and
